E. H. STEINER BOAT VENTILATOR Filed July 19, 1960 INVENTOR. EMR-I H. STEINER United States Patent- O 3,031,943 BOAT VENTILATOR Emri H. Steiner, 2181 Wallace Ave., Bronx, N. Filed July 19, 1960, Ser. No. 43,911 1 Claim. (Cl. 98-13) This invention relates to a device adapted to be. installed in the outer Wall or deck of a boat or the like to provide light at all times and air when desired, in an enclosed room therein, such as the rest room.

A principal object of the invention is to provide a device that can readily be installed in an opening formed in the outer wall or deck of a boat or the like for providing light and air in a room therein.

Another object of the invention is to provide a device of this kind with means for readily sealing off the room or the like from the atmosphere when desired.

A further object of the invention is to provide a ventilating device of this kind that can be easily manipulated from the inside of the boat.

It is also an object to provide a device of this kind that can be formed completely of plastic material.

It is also proposed to provide a device of this kind that can be formed of colored plastic materials for protecting the eyes from the suns rays.

Yet another object is to provide a ventilating device of this kind that is simple in construction, economical to manufacture and is highly eflicient for the purposes intended.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a secitonal view of a portion of a hood of a boat showing a ventilating device embodying my invention installed therein.

FIG. 2 is an enlarged top plan view of the ventilating device per se.

FIG. 3 is a cross-sectional view on the line 3-3 of FIG. 2.

FIG. 4 is a bottom plan view thereof.

FIG. 5 is a disassembled side elevational view thereof.

FIG. 6 is a top perspective view thereof with the hood removed.

Referring in detail to the various views of the drawing, in FIG. 1 there is shown a portion of a hood 10 of a boat with a circular opening 12 therein and with a ventilating device 14 made in accordance with the present invention installed thereover.

The ventilating device 14 comprises a flat circular plate 16 with a central opening 18 concentric with opening 12. The plate is formed of plastic material such as a thermoplastic resin and which is preferably transparent and colored and of considerable thickness. A veritcally disposed annular wall or flange 20 is seated on the plate around the opening 18, extending outwardly thereof with its inner end fastened to the plate by adhesive or in any other suitable manner. A passage 22 is thus provided through the opening 18 and annular wall 20. The plate is fastened to the top surface of the hood 10 by means of plastic screws 24 passing through spaced openings 26 formed in the plate adjacent the periphery thereof and plastic nuts 28 on the inner ends of the screws.

In accordance with the invention, means is provided for selectively closing and opening the passage 22. This means includes a narrow elongated slat 30, of similar plastic material, spanning the space across the opening in the annular wall 20 and fastened at both ends thereof 3,031,943 Patented May 1, 1962 to. thewall adjacent its outer end by means of plastic pins 32. A plastic screw 34 is rotatably jou-rnaled in the slat 30, midway its ends. and extends axially of the opening in the annular wall 20 on both sides of the slat. A circular plastic actuating knob 36 is fastened to the inner end. of the. screw 34 on one side of the strip and a circular disk 38: of similar plastic material is fastened to the other end of the screw on the other side of the slat by a plastic nut 40. The disk is formed with a tapered peripheral .edge 42. The diameter of the disk is substantially the same as the. diameter of the outer end of the wall 20 so that it is adapted to seat thereon and seal the passage 22 from the atmosphere.

In operation of the device, by turning the knob 36 in one direction, counterclockwise as viewed in FIG. 2, for example, the disk 38 will be moved away from the top edge of the center annular wall 20, permitting air to enter between the top edge of the wall 20 and the disk 38 and to pass inwardly through the passage 22 in the center wall 20 and opening 18 in the plate 16 into the room or other enclosure.

By turning the knob 36 in the opposite direction, clockwise as viewed in FIG. 2, the disk 38 will be moved toward the top edge of the wall 20 and continued turning in this direction will seat the disk on the top edge and seal the passage 22 from the passage of air therethrough.

The invention also contemplates protecting the wall 20 and disk 38 from the weather and seas and for this purpose a dome cover 46 is provided. The transparent dome cover has a semi-elliptical body 48 terminating at its periphery in a flat annular flange 50. The flange is provided with spaced holes 52 spaced similarly to the spacing of the holes 26 in the plate 16. When the dome cover 46 is in operative position over the plate, the holes 52 and 26 are in alignment and the screws 24 are passed through the aligned holes, spacing sleeves 54 of plastic having first been sleeved over the screws between the flange 50 of the dome cover 46 and the plate 16 to space the flange of the dome cover away from the plate to provide a passage 56 for the air to enter and circulate. The screws 24 fasten the dome cover 46 and plate 16 in position on the hood 10. When the dome cover 46 is in position as shown in FIG. 1, the air enters between the plate 16 and flange 50 and dome body 46 and circulates around the central wall 20 and when the disk 38 is in open position, the air enters underneath the disk and inwardly through the passage 22 constituted by the opening in the annular wall 20 and the opening 18 in the plate 16 and into the room or other enclosure. The transparent colored plate 16 and dome cover 46 permit light rays to enter into the room to illuminate the room but protect the eyes of the occupants from the rays of the sun.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent 1s:

A device of the character described comprising a circular transparent plastic plate adapted to be secured to the hood of a boat over an opening in said hood, said plate having a central opening in line with the opening in the hood, a tubular annular Wall seated on the plate and secured thereto around the opening therein, a narrow slat extending across the space in the annular wall at the outer end thereof, a screw member rotatably journalled on the slat midway its ends, and extending on both sides of the slat, a disk carried on the outer end of the screw, a

knob on the inner end of the screw for manipulating the same whereby the disk may be carried toward and away from the outer end edge of the annular wall for sealing and Opening the passage in the annular wall, respectively, and a transparent plastic cover for the outer open end of the annular wall and the disk secured to the circular plate in spaced relation thereto for protection against weather and seas and for illumination purposes, said plastic cover including a dome-shaped body terminating at its periphery in a flat annular flange, the periphery of the flange commensurate with the periphery of the circular plastic plate, said flange and circular plate having aligned holes, screws extending through said holes and aligned holes in the hood for securing the plate and plastic cover to the hood, and sleeves around the screws between the annular flange and circular plate for spacing the flange and dome-shaped body away from the circular plate and outer end of the tubular central wall.
